Abstract
The relation between the density of a randomly distributed wireless sensor network node and the node’s energy consumption is discussed, and the result shows that the way to extend the network lifetime is to deploy sink nodes in the field with a larger density of sensor nodes. Furthermore, the RDF algorithm a simple, effective and highly efficient strategy for deploying sink nodes, is proposed in this paper based on simulation results. The said algorithm determines the sink node location by giving reference for a large density of sensor nodes. Additionally, the sink node deployment can be efficiently achieved through dividing the region of network and the sink node communication range. Lastly, through simulation verification, the RDF algorithm deployment strategy is further proved valid and effective from the perspective of network lifetime and message delivery rate.
Highlights
As the heterogeneous node of a wireless sensor network has higher energy, larger quantities of resources and stronger processing capacity, its deployment in a wireless sensor network greatly exerts an influence on the data forwarding and energy consumption of the entire network
There are a number of researches of heterogeneous node deployment in wireless sensor networks
The recursive algorithm for heterogeneous node deployment in wireless sensor networks is proposed by reference [10] and [11], and this algorithm follows the basic procedure of deploying relay node in the network where sensor nodes are in large density
Summary
As the heterogeneous node of a wireless sensor network has higher energy, larger quantities of resources and stronger processing capacity, its deployment in a wireless sensor network greatly exerts an influence on the data forwarding and energy consumption of the entire network. Reference [2] puts forward two algorithms; one is a global algorithm deploying sink nodes on the basis of global information, and another one is a 1hop algorithm based on neighboring node information Through applying both of these, the network lifetime can be extended. References [4] and [5] clarifies that the process of moving a sink node allows a node to remain in conformity with the energy consumption status and distribution status so as to extend the network lifetime. These pertinent research projects meet the requirement of moving sink nodes. A more efficient and more convenient algorithm deploying heterogeneous nodes is proposed in this paper on the basis of a heterogeneous node deployment strategy
